[resolved] Page attributes/child page not showing (3 posts)

Hi, I'm a complete novice with WordPress, hope you can help.
Just set up a new web site using a Responsive theme. I've added a new page and selected About as it's parent but when I refresh the live page it doesn't appear under About, however on the Pages section of the admin screen it shows as being located under About. I'm baffled, hope you can help.
Thanks
